The Bose 121011 901 Speaker/Driver is a high-performance component that delivers stunning audio quality for music and home theater systems. This 2-ohm, 10-inch woofer is an essential part of the iconic Bose 901 speaker system, known for its ability to produce deep, clear bass and natural midrange and treble frequencies.
The woofer's powerful neodymium magnet provides the necessary force to move the driver cone, producing impressive sound pressure levels. The magnet's size and design contribute to the speaker's ability to reproduce low frequencies with precision and accuracy.
The cone of the 121011 901 Speaker/Driver is made of a proprietary, lightweight material called Kevlar. This material is known for its exceptional strength-to-weight ratio, making it ideal for speaker cones as it allows for a more responsive and efficient driver. The cone's shape is also engineered to reduce distortion, ensuring that the sound produced is clean and detailed.
The woofer's voice coil is made of aluminum wire, which is known for its high conductivity and low mass. This combination results in faster response times and improved efficiency, leading to more accurate and dynamic sound reproduction. Additionally, the voice coil is cooled by a large, copper-clad aluminum former, which dissipates heat effectively, ensuring the driver's performance remains consistent even during long listening sessions.
The 121011 901 Speaker/Driver also features a cast-aluminum frame that adds rigidity to the design, reducing resonance and vibration, and improving overall sound quality. This frame also provides a solid mounting point for the driver, ensuring that it remains securely in place and maintains its alignment with the other speakers in a system.
In summary, the Bose 121011 901 Speaker/Driver is a high-performance component designed to deliver deep, clear bass and natural midrange and treble frequencies for music and home theater systems. Its powerful neodymium magnet, Kevlar cone, aluminum voice coil, and cast-aluminum frame work together to provide impressive sound pressure levels, fast response times, and accurate and dynamic sound reproduction.
